UNO R3 ATmega328P Development Board with USB Cable

Build and test your next electronics idea with an UNO R3 development board based on the ATmega328P. Digital and analogue connections give you practical starting points for sensors, switches and other compatible modules.

Turn an electronics idea into a working prototype

• ✅ Connect inputs and outputs — 14 digital I/O pins support compatible switches, indicators and control circuits.
• ✅ Read analogue signals — six analogue inputs let suitable sensors become part of your project.
• ✅ Start with a familiar platform — the UNO R3 format supports projects developed for compatible Arduino hardware.

Board: UNO R3. Microcontroller: ATmega328P. Logic level: 5 V. Digital I/O: 14. Analogue inputs: six. Clock: 16 MHz. Package includes one board and a USB cable; base/case accessories depend on the selected option.
